I'm always on the lookout for beautiful vintage Japanese fans, and this is really a striking one. I am fairly certain it is the work of Keisuke Serizawa (1895 –1984), a Japanese textile designer (and National Treasure) renowned for his stencil patterns and dying techniques applied to the creation of kimono, paper prints, wall scrolls, folding screens, curtains, calendars, and fans like this one. These Keisuke Serizawa fans have become fairly rare to find and are quite distinctive. I believe its is squash of various sort that are represented, lushly executed in a super elegant and interesting palette. The backside is plain, and the fan structure is made of bamboo, with a nice round handle.
16 3/8" tall x 11 1/8" wide x 1/2" deep. Very good vintage condition, with one tiny tear on the bottom left edge where the print is stitched to the fan structure; very minor.
